Claims priority, application Belgium October 3, 1950 2 Claims. (Cl.68-498) This invention relates to a new type of support and spacer forbobbins for textile fibers, filaments, yarns or cloth wound in the formof cheeses, cakes, cones, spools, rolls, etc. More particularly, itdeals with supports and spacers for flexible bobbins, such as forexample the type decribed in my U. S. A. Patent No. 2,158,889, issuedMay 16, 1939 and in my copending application S. N. 213,251, filedFebruary 28, 1951, and now Patent No. 2,614,764 of October 21, 1952.These supports and spacers are employed for centering and spacing spoolsmounted in columns for the fluid treatment of the textiles wound on saidspools, such as for example, for the dyeing of the textile filamentsand/or fibers.

It is known that bobbins of nylon and rayon threads or yarns become hardduring fluid treatment due to their inherent elasticity and swelling inthe presence of humidity. This contraction often deforms the bobbinsupon which these yarns are wound. Also bobbins for fine threads whichare only wound to spools of a relatively small outside diameter, bellyin and/or out along their length when longitudinally compressed forfluid treatment. These deformations materially aflect the uniformity ofthe fluid treatment and the amount of the color taken up by the yarnswhen being dyed.

It is an object of this invention to produce a simple, eflective,efficient, economic, non-corrosive and metallic textile bobbin supportand spacer which prevents the deformation of spools of yarn wound onflexible porous bobbins, when said spools are mounted for fluidtreatment.

Another object is to produce such a support and spacer which preventsthe treating fluid from flowing between adjacent spools of yarn whenstacked in columns, and directs the fluid through the threads, insuringtheir uniform treatment.

In accordance with this invention, the support and spacer for the porousbobbins comprises an annular plate with an outer peripheral flangeforming a type of annular trough into which the end of a bobbin fits,and a perforated preferably cylindrical sleeve attached at one end tothe inner edge of said annular plate and extending in the same directionas the flange, for a greater axial distance than said flange, andpreferably at least almost half the length of the bobbin for which thesup port is to be used. When forming a column of such bobbins, abuttingpairs of these spacer supports, may be joined together with theirannular plates back to back to form unit pairs.

These spacer supports are adapted to be placed inside each end of aflexible bobbin and then they are strung with the bobbins on aperforated tube to form a column of spools. This column may then becompressed until the outer ends of the perforated cylindrical portionsof the supports touch each other, which can be the predetermined limitof compression for the spools being treated, beyond which limit thespools become too hard. The outer diameter of said cylindrical portionsof the supports, if desired, may be sufliciently smaller than the insidediameter of the flexible bobbins to permit contraction of the bobbinsand loosening of the center threads in the bobbins; and the innerdiameter of said cylindrical portions preferably are just sufficientlylarge enough to slide easily over a perforated tube acting as the axisfor the column of spools through which tube the treating fluids pass.

The above and other features and objects of. this invention and themanner of attaining them will beice ' come more apparent and theinvention itself will be best understood by reference to the followingdescription of a specific embodiment of the invention taken inconjunction with the accompanying drawing, wherein:

Fig. 1 is a longitudinal section of a unit pair of the support andspacer members according to one embodiment of this invention;

Fig. 2 is a section taken along line II-II in Fig. 1; an

Fig. 3 is a vertical section of the ends of a column of spools of yarnwound on flexible bobbins supported and spaced by the members shown inFigs. 1 and 2, and strung on a perforated tube ready for fluidtreatment.

Referring to the drawings, the annular plate 5 may be provided with anintegral up-turned outer peripheral flange 1 perpendicular to said plateand forming a cylindrical ring around said plate. Around the innerdiameter of the plate is mounted, such as by soldering or preferablywelding, one end of a perforated cylinder 3, having perforation slots 6extending from the plate 5 to short of the outer end of the cylinderwhere there is formed a continuous ring 7. The end of this cylindricalportion 3 may be provided with an outward radially extending flange 4 tofacilitate its attachment to the plate 5. Such comprises the half of theunit pair of supports shown in Fig. 1 or the support 11' shown in Fig. 3used at the ends of the column. As seenin Fig. 3 the cylindrical portion3 of this embodiment has a length of less than half the length of abobbin 13 to permit longitudinal compression of the bobbin. Betweenadjacent bobbins in the column in Fig. 3, pairs of abutting spacersupports 11 may be joined together, such as by solder or preferablywelding, to form a unit pair as shown in Fig. l, which joint alsoprevents treating fluids from passing between the abutting plates 5 andbetween the spools in the column thereby directing the fluid into thethreads of the spools.

In Fig. 3, the supports and spacers of this invention are shown in usein a column of spools ready for fluid treatment, which spools are woundon flexible porous bobbins of the type mentioned in the above citedAnnicq patent. These bobbins are fitted over the supports 11 and 11 withthe ends of the bobbins fitting in the annular channels formed betweenthe perforated cylindrical portions 3 and the cylindrical flanges 1. Thesupports 11 and 11' are then strung along a perforated tube 10 with thesingle supports 11' at each end to complete the column. The center oraxis tube 10 for the column may be provided with numerous holes 19 whichpermit the treating fluid to flow through them and then through theapertures 6 in the supports 11 and 11. The lower end of the tube 10 isshown to be exteriorly threaded for clamping in one wall of a fluidconducting channel 18. The other or upper end of the tube 10 is shownherein to be threaded interiorly for axially or longitudinally adjustingthe threaded disk 17, which supports the upwardly projecting threadedrod 16. Over the top of the tube 10 is placed a cap and plate member 14,which has a central hole for the rod 16, so that a nut 15 may bethreaded on said rod 16 above said cap to press the top plate down tocompress the spools 12 of yarn in the column until the supports 11 and11' have their outer cylindrical ends 7 substantially touching eachother as shown. The nut 15 also thus maintains the spools compressedduring their fluid treatment.

As shown in Fig. 3, the outside diameters of the cylindrical portions 3of the supports 11 and 11 are sufiiciently smaller than the insidediameters of the bobbins 13, so that they may be put on the bobbinseasily and will permit a limited amount of radial contraction of thebobbins 13. The inside diameters of the supports 11 and 11' are onlysufliciently larger than the outside diameter of the tube 10, so thatthey may be strung on the tube 10 and yet not permit side-play to causeunalignment of the supports, bobbins and spools.

The treating fluid, such as a dyeing solution, may pass through thechannel 18, tube 10, perforations 19 and 6, the links of the bobbins 13and uniformly around the threads of the spools, without being chanelledthrough some parts of the spools more than-others.

Although the present description is directed to spacer of a unitpair,-may be replaced by aperforated frustm cone having a lengthonly slightlyIeSs-than that-Oi 't he frusto-conical bobbin itself,--while the lowerhalf of the cylindrical portion 3 'below'the plate'S, may be replaced bya short cylindrical sleeveofsmaller'. diameter for cooperation with thesmaller end of the conical-portion'of the next adjacent spacer supportin the column.

' These spacer-supports ofthis invention are simple, and cheap to makein that they may be punched out of sheet material or from sheet materialand-tube-sto'ck, and then soldered or welded together. 'Thesheetmaterial is preferably anon-corrosive metal-, such as stainlesssteel, which although initially slightly more expensive than othermaterial, more than compensates for this- -cost-byits' durability andlonglife in-use.

"The spacer supports ofthisinvention alsomay be used advantageously forany type of longitudinally and/or axiallyflex-ible bobbins upon whichany kind ofifilament or spun yarn may be wound, artificial or-natural,such as nylon, rayon, fibro, cotton;- linen, wool, etc., whether suchyarn contracts, stretches or deforms or'not during winding and/or fluidtreatment.

While there is described above theap'rinciplesr of this invention inconnection with specific apparatus,it' is to; be clearly understood thatthis-descriptionismade-only byway of example and not asa-limitationtothe scope of this invention.
